Mu isi y’ubuhanga mu by’ubuhanga—waba urimo kubaka utwuma duto tw’ibikoresho by’ubuvuzi, guhuza ibice by’urumuri, cyangwa kugenzura ibikoresho by’indege bidashobora kwihanganira cyane—imbibi y’amakosa ni nto cyane. Nyamara abahanga benshi birengagiza ikintu cyoroshye ariko cy’ingenzi gishobora kwangiza bucece ndetse n’imikorere igezweho: ubuso bw’aho bakoresha buri munsi. Ntabwo buri gihe ari uburyo bugezweho bw’ibikoresho byawe; rimwe na rimwe, ni ukumenya neza ko biri munsi yabyo. Kandi iyo umwanya ari muto cyangwa imirimo ari mito, icyuma gikwiye gishobora kugira icyo gihindura.
Nubwo ameza manini yo kugenzura granite ari yo yiganje muri laboratwari zo gupima, amaduka mato, amashami y’ubushakashatsi n’iterambere, n’amatsinda ashinzwe serivisi zo mu murima arushaho kwishingikiriza ku mbuga nto kandi zo mu rwego rwo hejuru za granite kugira ngo barebe neza aho umwanya w’intebe ari muto kandi ubushobozi bwo gutwara ibintu bugomba kuba ingenzi. Ibi si ibikoresho "bito"—ni ibisubizo byubatswe ku ntego bigamije gutanga ubuziranenge n’imikorere myiza nk’iy’ibindi bikoresho binini, gusa byashyizwe ku rwego rwo hejuru kugira ngo bikoreshwe neza. Bihujwe n’ibikoresho byizewe.ibikoresho byo gupima granite—nk'ibipimo by'uburebure, ibimenyetso by'ubugari, ibipimo by'ubugari, n'ibipimo by'ubugari—agace gato k'ubuso gahinduka akantu ko gupima ibintu gashobora kwimurwa, bigatuma ibipimo biboneka aho ari ho hose kuva ku igorofa ry'umusaruro kugeza ku ntebe y'icyumba cyo gusukura.
Ariko dore ikibazo: ingano ntigukuraho inshingano zo gupima. Kimwe na sisitemu nini, izi referensi nto zisaba gupima ubuso bw'imbonerahamwe buri gihe kugira ngo zikomeze kwizerwa. Guhinduka kwa mikoro 5 gusa ku isahani ya mm 200 x 300 bishobora gusa nkaho ari bike cyane - kugeza igihe upimye ubushobozi bwa mm 0.01 ku munwa w'icyuma gitera lisansi cyangwa ugahuza icyuma gifata wafer ya semiconductor. Kuri urwo rugero, ndetse na microwarpage cyangwa kwangirika kwaho bishobora kwinjira mu bipimo bitari byo, gusubiramo, cyangwa kutagaragara neza. Niyo mpamvu inganda zikomeye zifata buri referensi ya granite - uko ingano yayo yaba iri kose - nk'ikintu cyagenwe, atari gusa isafuriya y'amabuye yoroshye.
Ubumenyi bw'ubu buryo bwo kwizerwa buri mu miterere ya granite yirabura yo mu rwego rwa metrology ubwayo. Bitandukanye n'icyuma gikozwe mu cyuma cyangwa icyuma, gikura uko ubushyuhe buhinduka kandi kikangirika uko igihe kigenda gihita, granite itanga ubuziranenge budasanzwe. Ingano yayo yo hasi y'ubushyuhe (ubusanzwe 6–8 µm/m·°C), ubucucike bwinshi (~2.97 g/cm³), hamwe n'imiterere karemano yo kuzunguruka bituma iba nziza cyane mu kazi gatunganye. Iyo ishyizwe ku rwego rwa 0 cyangwa 00 nk'uko biteganywa na ISO 8512-2 cyangwa ASME B89.3.7, icyuma gito gitanga imiterere nyayo ya geometrike iguma ihuye mu bihe bisanzwe byo gukoreramo.
Uku guhuza niko gutuma habaho ukuriameza ya graniteinzira zo gupima. Waba urimo kuzunguza ibice bya gage kugira ngo ushyireho umuhanga mu gupima uburebure, ukareba ubugari bw'ubugari ukoresheje plaque y'inguni isobanutse neza, cyangwa ukoresha ikimenyetso cy'inyuguti ya lever kugira ngo wemeze ko imiterere y'ubuso bw'ibanze ari nziza. Niba atari byo, buri gipimo gihinduka icyo kibazo - bucece kandi butagaragara. Niyo mpamvu sisitemu nziza zo ku rwego rwo hejuru zitari zifite ubuso bwa granite gusa; zigaragaza amateka yazo yo gupima, zikagenzura ibidukikije byazo, kandi zikabihagarika gusa iyo gusubiramo gupima byemeza ko byarenze imipaka yemewe.
Muri ZHHIMG, twakoranye n'abakiriya babanje kwanga ko hakenewe icyuma gito cyemewe, tuvuze ko intebe y'abakanishi babo cyangwa igice cya granite byari bihagije. Umwe mu bakora ibikoresho by'ikoranabuhanga mu Budage yavumbuye ko uburyo bwo gupima ibyuma butari bwo bwakoreshejwe bwavuye ku gice cy'icyuma cya aluminiyumu cyari gifunze neza bari bamaze imyaka myinshi bakoresha. Nyuma yo guhindura icyuma gito cy'ubuso cya 300 x 450 mm gifite icyemezo cyuzuye cyo gupima, ubushobozi bwo kongeramo ibikoresho bwazamutseho ibirenga 60%. Ibikoresho byabo ntibyahindutse—ariko fondasiyo yabo yari yarahindutse.
Ikindi cy'ingenzi ni uburyo izi plaque nto zihuzwa n'ibikoresho bigezweho byo gupima granite. Ibipimo by'uburebure bya digitale, igereranya ry'amatara, ndetse n'amaboko ya CMM atwarwa akenshi bisaba icyerekezo gihamye kandi gihamye cyo gushyiraho cyangwa kugenzura. Plaque ntoya nziza ikora nk'icyo gikoresho, igenzura ko imiterere yayo idahungabanywa n'ubuso butaringaniye cyangwa buhindagurika mu bushyuhe. Ku batekinisiye bo mu kibuga bakora imirimo yo gusana cyangwa gupima aho hantu, plaque ya granite itwarwa iba ihame rigendanwa—bizana icyizere cyo mu rwego rwa laboratwari ahantu kure.
Kandi bitandukanye n'ibyo abantu benshi bemera, granite ntabwo ipfa kwangirika mu buryo bufatika. Nubwo ishobora gushwanyagurika iyo ikubiswe n'icyuma gikomeye, irarwanya cyane kwambarwa buri munsi. Ntigira ingese, ntisaba amavuta, kandi ntizahinduka bitewe n'ubushuhe. Iyo ubyitayeho by'ibanze—gusukura buri gihe ukoresheje inzoga ya isopropyl, kwirinda gukomeretsa cyane, no kuyibika neza—ishobora gutanga serivisi yizewe mu myaka ya za mirongo. Amasahani menshi twabonye mu gihe cyo kuyikoresha kuva mu ntangiriro za 2000 aracyahuye n'imiterere yayo ya mbere y'ubugari, bitewe no kuyikoresha neza no kuyipima ku gihe.
Mu gihe uhitamo icyapa gito cy'ubuso, reba kure y'ingano. Emeza neza urwego rw'ubuso buto ukoresheje icyemezo nyacyo—ntabwo ari ibirego byo kwamamaza. Menya neza ko granite ifite ibice bito, igabanya stress, kandi nta mitsi cyangwa imitsi ya quartz ishobora kugira ingaruka ku busugire. Abatanga ibicuruzwa bemewe batanga inyandiko zuzuye, harimo n'ikarita y'ubuso buto igaragaza intera iri hagati y'ubuso n'ikibaya. Ku bikorwa by'ingenzi, tekereza ku byapa bifite inomero z'uruhererekane n'ibyemezo byo gupima bya NIST kugira ngo byuzuze ibisabwa mu igenzura rya ISO 9001 cyangwa AS9100.
Muri ZHHIMG, twemera ko ubuziranenge budakwiye guharirwa laboratwari nini zifite umwanya utagira umupaka. Niyo mpamvu dutanga ubwoko butandukanye bw'ibisubizo bya mini surface plate—buri kimwe cyapimwe ukwacyo, gishyirwa mu byiciro, kandi cyemejwe hakurikijwe amahame mpuzamahanga. Dufatanya n'amahugurwa y'abahanga ahuza tekiniki gakondo zo gupfunyika intoki hamwe n'uburyo bugezweho bwo kugenzura interferometric, kugira ngo buri plate yuzuze urwego rwayo rwavuzwe. Kandi kubera ko twumva ko gupima bikomeje, dutanga ubuyobozi ku bihe byo gusubiramo imiterere na serivisi zo gushyigikira kugira ngo ubuso bwawe bukomeze kuba bwizewe mu myaka iri imbere.
Kuko amaherezo, ubuziranenge ntabwo ari ukureba ubunini—ni ukureba ukuri. Waba upima icyuma cya turbine cyangwa micro-gear, amakuru yawe ni ukuri nk'uko ubuso bwubatsweho. Ntureke ko ibintu byoroshye bibangamira icyizere. Isahani nto y'ubuso icunzwe neza, ikoreshwa hamwe n'ibikoresho byo gupima granite byagenzuwe kandi ishyigikiwe no gupima ameza y'ubuso bisanzwe, si ikintu cy'akataraboneka—ni inkingi ikomeye yo gupima neza.
Ibaze rero uti: iyo usoma ibintu by'ingenzi cyane uyu munsi, uzi neza ko ubuso bwawe buhagaze neza — cyangwa urimo ukeka? Muri ZHHIMG, turagufasha gusimbuza gushidikanya ukabona ko nta gushidikanya — mikoro imwe imwe.
